[PATCH net-next] cxgb3/l2t: Remove unused t3_l2t_send_event

From: linux
Date: Mon Jun 09 2025 - 11:24:03 EST


From: "Dr. David Alan Gilbert" <linux@xxxxxxxxxxx>

The last use of t3_l2t_send_event() was removed in 2019 by
commit 30e0f6cf5acb ("RDMA/iw_cxgb3: Remove the iw_cxgb3 module from
kernel")

Remove it.
